Abstract: To separate drugs within a chamber (66) formed beneath a dome-like housing (24) from another biomedically active substance, the chamber (66) is subdivided into two chamber portions (166, 266) by enclosing, within said chamber, a plastic bag (101) or by stretching a membrane (102) thereacross. The plastic bag, or the membrane, respectively, is ruptured upon depression of a terminal element (34) located at the apex of the dome of the housing. The subdivision of the chamber into two chamber portions prevents intermixing of the biologically active substances during storage. One of the chamber portions may retain liquids which are suitable in the article, and preferably are separated from another one of the liquids, such as a surfactant, and thus permits a wide choice, of, respectively, biologically active and other substances. Unintended leakage of the substances through a microporous membrane (76) closing off the housing is prevented by applying a cover strip across the membrane.

Abstract: To separate electrolyte (70) within a chamber (66) formed beneath a dome-like housing (24) from a signal transmission connector (34) and thus prevent corrosion of the terminal portion (38, 40) exposed to the interior of the chamber by the electrolyte, the interior of the chamber (66) is subdivided into two chambers (166, 266) by enclosing within said chamber a plastic bag (101) or stretching a membrane (102) thereacross, the subdividing means (101, 102) being ruptured upon depression of the contact terminal (34) of the housing; the electrolyte is retained solely within the chamber (266, 266a) separate from the interior portion (38, 40) of the terminal so that the corrosive influence of the electrolyte is prevented from attacking the metal of the terminal prior to use of the electrode, and during storage.

Abstract: A heat producing device utilizing solid carbonaceous material, especially material of cellulosic composition such as corn cobs, as fuel. The heat producing device includes a gasifier for the carbonaceous material. The gas outlet of the gasifier leads to a burner. A cyclonic burning chamber and particle separator are connected to the discharge of the burner. The cyclonic burning chamber and particle separator has a heat outlet and a particle discharge outlet. An adjustable air inlet and mixing chamber are installed in the heat outlet for adding ambient air to reduce the temperature of the heat discharged from the heat outlet. A discharge fan has an inlet connected to the mixing chamber and an outlet for discharging the heat received therefrom to a drying chamber or other heat utilizing source.
